### Official description

LGSL (Live Game Server List) provides online status for games. Before 7.0.0, a stored cross-site scripting (XSS) vulnerability was identified in lgsl. The function lgsl_query_40 in lgsl_protocol.php has implemented an HTTP crawler. This function makes a request to the registered game server, and upon crawling the malicious /info endpoint with our payload, will render our javascript on the info page. This information is being displayed via lgsl_details.php. This vulnerability is fixed in 7.0.0.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
